I had a miscarriage 2 weeks ago whats wrong with me now?

Anyways after I stopped bleeding me and my husband have been ttc everyday since 4 days after miscarriage when bleeding stopped. It has been two weeks now still negative test, but I just started spotting in morning on tissue paper when I wipe. The same thing happened today. I have been getting off Klonopin and off of Paxil, and all kind of emotional crap is happening with his family being mean to me. He even tried to choke me and manhandle me when I went psycho (all the hormones and his family treating me like crap without his defending me). He is better now, but last night was a big fight full of emotion and me crying all night. Anyways this morning as I was laying bed on my side, my stomach started getting real hard like contraction but no pain, and nothing came out. I couldn't move and could hardly breath. Could this have been some kind of seizure or something else? I don''t know what's happening. This happened about 8 times. I couldn't get up or move. I didn't bite my tongue or anything. Yesterday morning I had some cramps and when I wiped a little blood on the tissue paper. The same thing this morning, but nothing coming out like a miscarriage. Could I be pregnant again? So far the pregnancy test is negative but I was wondering if I'm having implantation bleeding and if it will be positive later. If anyone has advice please let me know. I know I should call my dr. but his staff is rude and won't answer my questions most likely. I went ahead and took a klonopin just in case that is what was causing it by going cold turkey off my meds.
